Take a beautiful, and very deep, brick room and fill it, wall-to-wall, with a thick layer of soft, colorful yarn and thread waste and what do you get? A most unusual, and thoroughly fun, bouncy space where running, jumping, flipping through the air, turning summersaults, and of course, digging for treasure, are simply irresistible--and not just for kids. My five-year-old son wanted to stay all day. So did my husband.

You may be surprised to find that this fun is not in a play space or a children's museum, but at MoMA PS1, the contemporary art museum in Long Island City. Read on to find out more about this and some other exhibits at MoMA PS1 that will make checking it out in the exhibit's last weekend worth the trip.

I love taking my kid to see live theater. Over the years, we've seen shows from Broadway to the Fringe Festival, but the ones that have made the biggest impression on her are the productions at TADA! Youth Theater. Part of that is because she's watching her peers onstage: the children's troupe is made up of local youngsters ages 8 to 18. But I think my daughter loves TADA! for the same reason I do: Its original musicals are funny, sweet, thought-provoking and all around awesome. And the tickets are super-affordable:$15 for adults, $8 for kids.

We've written many rave reviews of past TADA! shows, so we're excited to offer a huge ticket giveaway for the company's entire 2012-2013 season. One lucky family will win four tickets to four TADA! musicals, including Up to You, which opens in April, and two runner-ups will snag seats to one or two shows. All told, over $500 worth of prizes!

Read on for more info on this wonderful kids' theater company, and the scoop on how to enter to win TADA! tickets.
